Description:

This Type-C USB Input High Current 3A Polymer Ternary Lithium Battery Quick Fast Charging Board, equipped with the IP 2312 main control chip, is designed for efficient and controlled lithium battery charging. It offers flexibility in charging currents and cut-off voltages, making it suitable for a variety of applications where fast and reliable battery charging is essential. Power up your lithium battery projects with speed and safety using this Type-C USB Lithium Battery Charging Module based on the IP2312 chip. Designed for 3.7V Polymer and Ternary Li-ion Batteries, this compact module supports Quick Charge (QC) and 3A fast charging, ensuring efficient and stable charging performance.

With Constant Current / Constant Voltage (CC/CV) charging and built-in safety protections, this board is ideal for DIY battery banks, wearable tech, and IoT devices. The USB Type-C input ensures universal compatibility with modern power sources and fast-charging adapters.

Features:

• The IP2312 uses a full CC/CV charging mode.
• When the battery voltage is lower than 3V, it enters the trickle charge mode and charges the battery with a charge current of 100mA.
• When the battery voltage is greater than 3V, enter the constant current charging mode to charge the battery with the set constant current charging current.
• When the battery voltage is close to 4.2V and the charging current is less than 300mA, it enters the constant voltage charging mode. After entering the constant voltage mode, the charging is stopped after every 4 minutes, and the battery voltage is detected to be higher than 4.15V: if it is higher than 4.15V, the charging is stopped; otherwise, the charging is continued, and then the detection is performed after 4 minutes.
• When the battery is fully charged, if it detects that the battery voltage is lower than 4.1V, it will turn on to charge the battery.
